Monthly Monster Mashup 4: Iron Golem + Water Elemental

One is unyielding metal. The other is flowing water. Put them together and you don’t just get a weird encounter—you get a myth. In this Monster Mashup, we explore what happens when a Water Elemental is trapped (or empowered) by an Iron Golem. From mystical hydraulics to ecological catastrophe, this combo creates enemies that your players won’t just fight—they’ll have to decide whether to break the cage or hold it closed.

Iron Golem: The Immovable Object

The Iron Golem, a CR 16 monster from the Monster Manual, poses a significant threat to adventurers. With powerful attacks, a poisonous gas ability, and high resistances, it is challenging to defeat. Often serving as guardians, their potential misuse by creative individuals could lead to destruction, requiring players to navigate complex encounters.
